- 摘要:
- 以药食兼用红花新株系‘3-10’为试材，研究了不同采收时间(35、40、45、50 d)对红花苗菜产量、黄酮及维生素C含量的影响，以确定红花苗菜的最佳采收时期。结果表明：50 d采收时红花苗菜净菜重达最高值，50和35 d采收结果有显著差异，但与采收时间为40、45 d的处理无显著差异；黄酮含量在采收时间为50 d时达最高值，采收时间为50、40、45 d的黄酮含量差异不显著，但分别与采收时间35 d处理之间有显著差异；在45 d时，其维生素C含量最高为22.43 mg/100g。因此红花苗菜采收时间为40～45 d较为适合，既保证了红花苗菜的产量，又提高了其营养成分含量。
- Abstract:
- Taking safflower vegetable ‘310’ strain as material，the influence of harvest time(35,40,45,50 d) on the yield and flavonoids and vitamin C content of safflower vegetable were studied，in order to determining the best harvest time of safflower seedlings.The results showed that the net weight of harvest time 50 d was the highest，there were obvious differences of net weight between harvest time 50 d and 35 d.No difference was found among the harvest time 40,45,50 d.The flavonoids content reached the highest level in harvest time 50 d.Differences among harvest time 50,40,45 d were not obvious，but significant differences did exist between harvest time 35 d and 40,45,50 d,respectively；but，the vitamin C content reached the highest level in harvest 45 d and was 22.43 mg/100g.According toguaranteeing output and improving the nutrient content，it was concluded that harvest time 40~45 d was more suitable.
